Patrol or Maestro for Flutter app testing? Here’s what you need to decide. 👉 leancode.co/blog/patrol-vs-m… Both solve the same problem with different architectures: Patrol runs inside your app’s process, while Maestro drives it from the outside. These are foundational decisions, not feature gaps. Read & understand the trade-offs. #FlutterDev #E2ETesting @patrol_leancode

While getting ready for the next edition of #FlutterTechSummit, we needed to check: How long would it take to get our FTS Flutter app ready for iPhone Duo? 👀 Turns out: only 1 day. ✨ #FlutterDev #iPhoneDuo

What if every mobile release could be an experiment-not a gamble? 🚀 At Nubank, feature flags help teams separate deployment from release, test ideas safely, and make rollout decisions based on real-world data.💜 Rafael Lisboa shares how they do it with Flutter. 🎥piped.video/watch?v=kqm0AOdc… #FlutterDev #FeatureFlag #FlutterTechSummit

Patrol has 600K downloads a month! 🤯 We started building this #opensource framework for agentic #E2Etesting for Flutter back in 2022 - and watching more and more Devs and QAs trust and use it every month means a lot to us. Thank you to everyone using Patrol, contributing, sharing it, and spreading the word. 💙

Flutter was missing from the SAP ecosystem. Not anymore! 🚀 Watch @Fiolek_'s talk about this solution: 🎥 piped.video/watch?v=8ajQkfLh… SAP powers the core processes of many enterprises, but its standard workflows rarely fit exactly how teams work. Custom apps can adapt #SAP to specific business needs, yet building them has traditionally been slow and complex. We bring SAP integration to Flutter. 💙 #FlutterDev #EnterpriseSoftware

I ran @LeanCodePl Marionette with @typesafeai Jev. One sentence: "win the game." A Flutter game it had never seen. 5 puzzles, rules only on screen. It read the code, flipped the right switches, tapped blue, red, green. 🤯 9.7 s. $0.0012. ⚡ No LLM involved. Marionette reads the widget tree and taps, Jev decides 🧵

9,000+ km to give a Flutter talk! ✈️🌎 Our Senior Flutter Dev, @PRogulskiDev, is heading all the way to Cancún, Mexico, to take the stage at @FlutterConfLAT! His talk, “Stop Being a Human Linter: Automating Flutter Architecture at Scale,” tackles a challenge every growing engineering team eventually hits: architecture guidelines shouldn’t live only in Confluence or rely on reviewers to catch every violation. 📍 Flutter Conf LATAM - Cancún, Mexico 🗓️ September 22-23 🎟️ flutterconflatam.dev #FlutterConfLATAM #FCL2026 #FlutterDev

Using Patrol? There’s a good chance you are, since it has 600K monthly downloads 🤯. But do you know all its capabilities? Or maybe you’ve only heard about it? Then it’s never too late to start. There’s an article about @patrol_leancode, including extra powers like test sharding, how to get better at using Patrol MCP, and more. 🌟 Worth checking out 👇 leancode.co/blog/everything-… #FlutterDev #E2ETesting #FlutterTesting

Hey, your conditional form sections don't have to be a mess :) advanced_forms lets you attach and detach subforms in one call, and the tree 🌳 nature of the form state means no more ifs in your validators. #FlutterDev

The Challenge: building reliable E2E tests for an app that depends on connected devices. 📱 Eduard Siewert (Sonova) & @oskar_lncd (LeanCode) show how Sonova improved test coverage and shortened release cycles with hardware simulation and AI-generated tests 🤖. See how Patrol MCP lets AI agents inspect the UI and write tests efficiently. ▶️ Watch the talk: piped.video/watch?v=5g66yqOF… #FlutterDev #FlutterTechSummit #E2ETesting @patrol_leancode

Your Product Owner's "small fix" 😇 the day before the client demo: switch form validation from "on submit" to "on unfocus." With @LeanCodePl's advanced_forms that's one line of code :) #FlutterDev

Look how little code & effort it took to create a sign in form with validation using advanced_forms 💪 Under a minute of work We built advanced_forms for the big painful forms, but it's great for the small ones too 💛 advanced-forms.leancode.co

Our team is back from @FlutterNFriends and, well… they were pretty busy there, thanks to you - if you attended. 😉💙 Flitz demos, 3 talks (delivered by @matiwojt, @albert_wolszon, Artur, @Fiolek_ ) & a Flutter E2E workshop with Marionette + Patrol MCP (by @oskar_lncd) & lots of great conversations. Btw. Oskar said that seeing around half the room already actively using @patrol_leancode made the workshop particularly fun. Our team also came back inspired: @schultek_dev & @parlough - Jaspr got some of us coding right away 😅, and @algebrandon’s GPU demo had the whole room silent. 👀 It really felt like Flutter AND Friends: technical, social, funny & full of people excited to build cool things. Thanks to everyone who stopped by! 💙 One feature request for next year: bring back Code in the Dark. 👀 #FlutterDev #FlutterNFriends26

Have you tried our #opensource package advanced_forms? Our team member @ksztandur is taking great care of it - and just released v0.2.1! 🚀 There's also a brand-new page with everything you need to get started and see what advanced_forms can do. #FlutterDev give it a try 💙
